Commercial pigs globally are routinely mixed into new social groups. This results in regrouping aggression predominantly during the first 24 h which compromises welfare and productivity. Chronic aggression persists thereafter ...

Mixing of growing pigs results in aggressive contests between group members. As aggres-sion serves to establish dominance relationships, it is possible that increased initialaggression may facilitate the formation of social ...

Over the past three decades, near infrared reflectance (NIR) spectroscopy has been proved to be one of the
most efficient and advanced tools for the estimation of quality attributes in meat and meat products. This
review ...

Methane produced from 35 Aberdeen-Angus and 33 Limousin cross steers was measured in respiration
chambers. Each group was split to receive either a medium- or high-concentrate diet. Ruminal digesta
samples were subsequently ...

The aim of this study was to assess individual differences in temperament and stress
response and quantify their impact on feed efficiency, performance, and methane (CH4)
emissions in beef cattle. Eighty-four steers ...

Fearful behavioral responses to handling (temperament) are undesirably associated with ADG and meat quality in infrequently handled Bos indicus cattle. It has never been assessed whether these relationships exist in calmer ...

The methane hood (MH) system is a novel method of quantifying methane (CH4) emissions from cattle during feeding. The MH system measures CH4 concentrations exhausted from beneath a hood designed to partially enclose the ...

Bayesian analyses were used to estimate genetic parameters on 5580
records of litter size in the first four parities from 1758 Mule ewes. To
examine the appropriateness of fitting repeatability (RM) or multiple
trait ...
